Abstract
Nafta je danas u svijetu jedan od najznačajnijih proizvoda. Najčešće se koristi za pokretanje vozila i u termoelektranama za dobivanje električne energije. Značajna je sirovina za dobivanje mnogih drugih proizvoda. Organskog je podrijetla. Dobiva se iz bušotina i tako neprerađena se naziva sirova nafta. Nakon izvlačenja na površinu, prolazi kroz procese čišćenja, separacije i preradbe kako bi se pripremila za transport. U procesima separacije odvaja se od naftnog plina koji se također dobiva iz bušotina. Tako prerađena nafta prenosi se cjevovodima do rafinerija. Na stabilnost njenog toka u cjevovodima utječu karakteristike cjevovoda kao što su: materijal od kojeg je cijev izrađena, područje na kojem je cijev postavljena (ispod ili iznad tla), dimenzije cijevi te razni vanjski čimbenici na koje ponekad ne možemo utjecati. Također na tok utječu i njena svojstva poput gustoće, viskoznosti i tlaka. Obzirom da se odvaja od plina prije transporta, tok nafte je jednofazan pa kao takav može biti laminaran i turbulentan. Transport nafte vrlo je važan za Republiku Hrvatsku zato što povezuje mnoge rafinerije okolnih zemalja sa hrvatskim rafinerijama. Dobra povezanost omogućava izvoz nafte i time priliku za gospodarski rast Republike Hrvatske.
Abstract (english)
Today petroleum is one of the most significant products in the world. It is mostly used as fuel and in thermal power plants for acquiring electric power. Also, it is commonly used in manufacturing other products. It is naturally occurring, furthermore it is mostly recovered by drilling and this unprocessed drilled fluid is called crude oil. After crude oil has been extracted, its components are separated, processed, refined, and prepared for transportation. In the separation process the liquid mixture is separated from the petroleum gas. That processed petroleum is transported through pipelines to refinery. Flow stability in those pipelines is determent by: materials used in pipeline construction and various environmental actors that cannot impact. Likewise, other factors such as fluid properties (density, viscosity, and pressure) also affect flow stability. Considering the fact that crude oil is separated into petroleum and its gas, it can be concluded that petroleum is single phased. Therefore, its flow can be laminar or turbulent. Petroleum transport in Croatia is of great importance because it connects neighbouring countries with Croatian refineries. Good transport connections allow Croatian economic growth.
